To all whom it may concern:

Be it known that LI, MILTON ASHTON FES- LER, a citizen-f the United States, residing at Visalia, in the county of Tulare and State of California, have invented certain new and useful Improvements in Crude-Oil Burners; and I do declare the following to be a full, clear, and exact description of the invention, such" as will enable others skilled in the art to which it appertains to make and use. the same. 1

' My invention relates to improvements in crude=oil burners of that class in which the ment of devices hereinafter described andclaimed.

The object of the invention is to provide a burne'rot this class with simultaneously-opcrating means'for regulating the discharge of both the oil'and the steam and for appropriately proportioning them so that the vapor produced by the burner will under all cQnditions consist of steam and oil coinmingled in Ithe proper proportions to give the best re sult.

In the accompanying drawings, Figure 1 is a perspective view of a crude-oil burner em bodying my improvements, showing the same in connection with a stove. Fig. 2 is a detail elevation showing my simultaneouslyo crating means forcontrolling the discharge Fig.3; 1

01' oil an steam. Fig. 3 is a sectionalview of-t'he same, and Fig. 4 is, a similar view taken on'the plane indicated'by the line an of The burner-body 1 has a steam-passage 2 and an oil-passage3. The former is provided with a suitable coupling, here shown as a sleeve 4,screwe'd to the'outer end thereof to connect a'steam-pipe 5 thereto. In Fig. 1 of the drawings the steam-pipe shown as leading from a b0iler.6,'whicl1 is disposed in the fire-box 7 of a stove The oil-supply pi e 8 is coupled, as at 9, to'th e oil-passage 3 an inchides-in the form of my invention shown in Fig. 1 a valve 10.1or the discharge of oil into a drip-pan 11, which'is also disposed in the 1 fire-box of the stov'e and the otlice of which is to produce initialheat for the purpose of v generating steam into-the boiler. The valve bore of which communicates atits inner end with the oil-passage 2 and has its outer end tapered, as M13, and reduced in diameter.

In the bore is a needle-valve 14, the stem 15 of which is screw-threaded for a suitable dis? tance, as at 16, and passes through and en'- gages the threaded bore of an arm 17, which projects from one side of the burnerbody.

aid arm is screw-threaded, as shown, and on the same is screwed. a sleeve-gland 18, through which the needle-valve. stem extends. The said sleeve-gland also. serves to compress suitable packing '19 to prevent leakage around the valve-stem. The latter is provided at its outer end with .a spurgear 20.

The nozzle 12 is screw-threaded, and on the-same is screwed a regulating and mixing shown as of the same diameter as the gear 20,

with which the needle-valve is provided.

An operating shaft 24 is journaled in a bearing 25, formed at one side of the burner body, is provided with a pinion 26, which engages. the spur-gear 20, has a pinion 27, which engages the spur-gear 23, and .i'sprovidcd at its outer endiwith a hand'wheel or other suitable device 2.8, whereby it may be readily r0- tatedi The said shaft also has a bearing in a l nk 29 which has a bearing also for the stem of theneedlewalve.

It will be understood thatby turning the shaft 24 the needle-valve and the'regulating and mixing nozzle will be caused to rotate si- -n'iultaneously therewith by ,means of the gears which connect tlfem, thereto and that said nozzle and needle-valve will be also moved lon 'tudinally, owing tothe screwthreads wit which they are provided, hence causing them to vary the efi'ectiveareas of the jet-openings as niaybe required.

It will be understood that my improved burner may be used in connection with any source of steam and of oil and that it may be used for other purposes than producing combustion in a stove, as here shown. Having thus described my invention, what I claim, and desire to secure byLetters Tatent, is-

A burner of the class described havin a threaded. needle valve to regulatethe iscl'iarge oi'steam, said valve bei IOVldQd with an operating-screw, -'a three e revolu-" ble regulating and mixing nozzle to govern In testimony whereof I have hereunto set the disohargeof oil, said nozzle mul-needlemyhanel ZlH-PLTBSGIICG of two subscribing wit-- valve each provided with a gear-wheel and nesses.
